Guillen said he will fly to Miami after Monday's game and explain his comments about Castro during a news conference on Tuesday at Marlins Park at 10:30 a.m. He invited anyone to attend who wants to ask a question or hear what he has to say. ESPN announced it will televise the news conference.

"Anybody who wants to be there, feel free," he said. "I don't want to make a statement because I think when you make a statement it's a bunch of crap. I want people to look at my eyes and look at my face and see what's going on, tell what the deal was, and that's it."

Guillen said he has been troubled and unable to sleep the past three nights since the story broke.

"I feel very guilty about it and very bad and sad and very embarrassed," he said.

Guillen has been under fire since reports surfaced that the upcoming edition of Time magazine quotes him as saying, "I love Fidel Castro."

He later amended his comment, saying: "I respect Fidel Castro. You know why? A lot of people have wanted to kill Fidel Castro for the last 60 years, but that [expletive] is still there."

On Monday, he continued to express regret.

"I feel sad and a couple days stuff in my stomach," he said. "Not because what I did, just because I know I hurt a lot of people. And I'm going to make it clear, especially for me. … I told the Marlins I want to fly as soon as I can. [Tuesday] is a day off. I'd rather be in Miami clear everything up. I think that's the best for everyone."

The Marlins are in Philadelphia for the Phillies' home opener and have an off day on Tuesday (built into the schedule in case opening day is postponed). They resume their schedule in Philadelphia on Wednesday.

Guillen said he has spoken to a number of people with ties to Cuba and offered apologies, including long-time Marlins Spanish announcer Felo Ramirez.

"The saddest part of this was to apologize to Felo Ramirez. That was hard. I did, face to face," Guillen said.

Ramirez and broadcast parnter Luis Quintana declined comment on Guillen's remarks about Castro. Ramirez said Guillen is taking the proper steps by returning to Miami and address the issue as soon as possible.

Asked if he was concerned the issue could cost him his job, Guillen said, "I hope not. Why? I'm Latino. I lived in miami for 12 years. I know how people feel about that. I've got a lot of friends, a lot of players [who] play for me, they know who I am. They know how I feel, what I mean."

Guillen didn't deny making the comments about Castro, but seemed surprised how his remarks were portrayed in the Time article.

"I don't want to put the guy in the spotlight. The interview was about sport, not politics," he said. "You read what it was, it comes out different way. I can't control that. I have to wear it, I have to face it. I have to grab the bull by the horns, and I will do it tomorrow.

"If [people] are disappointed or upset with what I said, I don't blame them, but I'm with them," Guillen said. "I lived in Miami for 12 years. I know exactly what [Castro] means to the town…"

The Cuban-American group Vigilia Mambisa plans to boycott and demonstrate against Marlins until Guillen steps down, according to a report on NBCMiami.com. A demonstration is planned at the new Marlins stadium in Little Havana on Tuesday.

Marlins first baseman Gaby Sanchez, the son of Cuban exiles, refused to comment about the planned protest in Miami or to disclose the feelings of he and his family.

"I'm here to play baseball. I'm not dealing with any things about politics or anything like that," Sanchez said. "I don't know what was said, I don't know anything that happened. You're not going to get anything out of me. If you've got other questions [about baseball], go ahead and ask, but I'm going to get into that."

The team issued the following statement last week: "We are aware of the article. There is nothing to respect about Fidel Castro. He is a brutal dictator who has caused unthinkable pain for more than 50 years. We live in a community filled with victims of this dictatorship and the people in Cuba continue to suffer today."
